scmutil: introduce function to check whether repo uses treemanifest or not

In an upcoming patch, I wanted to check whether current repo uses treemanifest
or not.
I looked for a function and found that at all places we manually check for the
requirement in repo requirements. I guess having a dedicated function for that
is much better.
